Tacrolimus (also FK-506 or fujimycin, trade names Prograf, Advagraf, Protopic) is an immunosuppressive drug used mainly after allogeneic organ transplant to lower the risk of organ rejection.
To make sure tacrolimus is safe for you, tell your doctor if you have: 1  kidney or liver disease; 2  heart disease, high blood pressure, high cholesterol or triglycerides (a type of fat in the blood); 3  a heart rhythm disorder or history of long QT syndrome;4  if you take heart rhythm medication; or.he immune system can also fight or reject a transplanted organ such as a liver or kidney. This is because the immune system treats the new organ as an invader. Tacrolimus is used together with other medicines to prevent your body from rejecting a heart, liver, or kidney transplant.
